WRAPPING MACHINE.

Application :filed July 19, 1926. Serial No. 123,443.

My chines, shown the invention being to wrap candy, such as l mints, orlike articles, in packages which preferably are of suitable form andsize to be dispensed through coin-operated vending machines.

While the machine of the invention, as will be apparent, is not in anysense limited to the wrapping of articles for vending machines, it hasbeen designed, in part, with a View to overcoming certain difficultieswhich have been experienced in dispensing, through such vendingmachines, articles which have been wrapped by the machinery heretoforeused for the purpose or by hand. It will be a preciated that in the caseof mints, or like articles wrapped according to the accepted custom,that is, in rows, wrapped with a suitable foil or other material whichextends beyond the ends of the rows and is twisted or otherwise closed,the dispensing of such packages through the passageways of vendingmachines would be seriously interfered with by irregular or projectingends on the packages, or by loosening of such ends with resultantdisarrangement and perhaps spilling out of the contents. In practice,this has frequently occurred and one of the most important features ofthe present invention is the provision of a wrapping machine which isadapted to close the -ends of such packages tightly and permanently, andwithout leaving any projecting folds or irregularities which mightinterfere with the dispensing of said packages in the mannerhereinbefore described. p

In this connection, it may also be mentioned that the particularlyeffective instrumentalities provided by the invention for closing theends of the packages render it possible to effect a very materialeconomy in the wrappers employed. This, operation has ordinarily beenperformed, when it has been done by machinery, by mechanism adapted tospin the ends of the wrapper and, -in order to get satisfactory resultswith this method, it has been found necessary to use an unlined foil,which, since it comes in direct Contact with the mints, orother articlesof food, must beof such character as to avoid possibility ofcontamination. For this reason, the relativey expensive tin foil hasordinarily been ernployed, but, when the-wrapping is performed by themachine of my invention, the considerably less expensive lead foil, witha wax paper lining (whi ch would prevent eective closing of the ends ofthe wrapper by the spinning method) may be employed, the combined costof the lead foil and lining less than the cost of the tin foil, .and thewrapper thus made being in'full compliance with th'e food laws.

A further object of the invention is the provision of full automaticmechanism for performing in suitably timed relation the severaloperations required for wrapping articles in packages of the typehereinabove referred to and the novelty of said mechanism resides in thegeneral combinations, as well as the specihcconstruction and principleof operation of certain elements to Vbe hereinafter more particularlypointed out and claimed.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

Upon said drawings, illustrating ythe best manner in which I have thusfar contemplated applying the principles of my invention, the referencecharacter 11 indicates a table upon which the machine is adapted to bepositioned and to which it is adapted to be secured by means of bolts12, extending through flanges 13 of uprights 14 supporting the operatingelements of said machine (see Figs. 1 to 3). A bed plate 15 is supportedby said uprightsto which it is secured by means of bolts 16 (see Fig.4). A power shaft 17 has bearings in the uprights 14 and carries at oneend a pulley 18, adapted to be driven from any suitable source of powerby means of a belt 19, a. fly wheel 21 being carried at the opposite endof said shaft. Said shaft 17 car-ries a clutch 22 (see Fig. 3) and isgeared to a cam shaft 23 by means of ring gears 24 and 25. Said camshaft carries at its opposite ends miter gears 26 and 27. mesh- V ingwith corresponding gears 28` and 29 secured respectively to vert-icalcam shafts 31 and 32- at the lower ends thereof. Said cam shaft 23carries a sprocket 33, connected by a supported by uprights 39'extending upwardly from the bed plate 15.

Referring now particularly to Figs. 2 and 6, the wrapper feeding andcut-olf mechanism will be described. A roll 41 of wrapping material, inthe present instance lead foil with a wax paper lining, is supportedfrom the uper ends of the side plates' 37, which are ormed with U-shapedrecesses 42 for the reception of studs 43 projecting laterally from aspool 44 upon which the wrapping material is wound. The web 45 from saidroll 41 is 'directed over a tensioning roller 46, carried by a yoke 47,which is pivoted to the plates 37 at 48 and has a. lower extension 49connected by a spring 51 to said plate 37, whereby the tensioning rolleris yieldingly held in extended position and adapted to take up suddenjerks or pulls on the web which might otherwise tend to sever the latterand necessitate stopping the machine. The web is directed fro-m thetensioning roller over al guide plate 5 2 and between feeding rollers 53and 54, mounted upon cross shafts 55 and 56, which carry at their outerends intermeshing gears 57 and 58. The gear 57 is adapted to beintermittently driven by means of a ratchet mechanism, shown clearly inFig. 2 and comprising a ratchet wheel 59, rigid with the gear 57, a pawl61, pivoted at 62 to one corner of a plate 63, pivoted to one of theside plates 37 at 63 and connected by a link 64 with a crank arm 65,carried by the shaft 36, the pawl 61 being held in engagement with theratchet wheel vby means of a spring 66 connected to the lower end ofsaid pawl and to the plate 63. It will be apparent that-'by means of themechanism just described, constant rotation ofthe shaft 36 will impartan intermittent or step motion to the gear 57, and consequently to thefeed rollers 53 and 54. Beyond said rollers 53 and 54, the web isthreaded between guide members 67 and 68, the latter being pivoted at 69to a frame part 71, which is slot-ted as indicated at 72 to permitrelative movement of the member 68 with respect to the member 67 (seeFig. 7). Said member 68 rests upon the .member 67 and on the web 45merely by its by said roller and associated mechanism are movable bodilyoutwardly and upwardly about the pivot 75 to facilitate the positioningof the roll 41, which may then be inserted from the front. A latchmember 76 is pivoted to the yoke 74 near the lower end of a centralmember 70 thereof and is adapted to automatically engage a cross pin 77,mounted in forward projections 8O on the frame, when link 96 and to thebar 77 the parts are returned to normal position, such automaticengagement being effected by means of a spring 78, connected with theyoke 74 and the inner end of the latch member 76, the latter beinglimited in its movement under spring tension by a pin 79 and being cutaway at the inner end to cause it to ride over the pin 77 when said yoke74 is brought down to the position shown in the drawings;

A spring-pressed wiper and friction pad 81 is carried by the bracket 73,being urged against the roller 54 bymeans of a spring 82, -mounted on ashank 83 of a pad holder 84,'

said pad serving to wipe oit the wax' which may accumulate upon theroller 54 by reason of its Contact with the wax paper lining of the web45 and also to provide friction upon said roller 54, thereby assistingin the feeding action. Suitable lengths of the web areadapted to be cutoff by means of a cutter bar 85 and co-acting edge block 86, the latterbeing inset in the lower side of the member 67 and the former beingpivoted at 87 to said block and being adapted to be actuated bymechanism shown most clearly in Fig. 2.

v A bellcrank lever 89 is pivoted at 91 to the upper part of the sideplate 37 and the lower arm 92 thereof is connected at 93 with a linkconnected by a vertical pivot 95 with a jointed link 96, pivotallyconnected'at 97 to the outer end of the bar 85. The upper arm 98 carriesa roller 99, riding upon a cam 101 carried by the shaft 36 near theouter end thereof. Said knife is normally held in the outer position bymeans of a spring 102 connected at its opposite ends to a pin on the n(see Fig. 2), said spring serving to hold the tact with the cam 101. Theform of said cam is such as to'cause the cutter bar 85 to eriodicallycut oti a wrapper of suitable length from the web 45, said wrapper beingreceived by a transfer mechanism, which will next be described,reference being had, in this connection, particularly to Figs. 2, 6, 7,8, 20 and 22.

l Opposed jaw members 103 and 104 are mounted on a horizontal axis, theform of said members being clearly shown in Fig. 22, from which it-willappear that they are biiurcated, the opposite sections 105 and 106thereof being mounted upon short shafts 107, journaledin uprights 108extending upwardly from a forward bracket 109 on the frame `(see Fig. 7rllhe upper jaw member 104 is loose on said shafts 107 and the lower jawmember is secured to said shafts, as indicated at 111 in Fig. 22.Friction lis provided upon one of said shafts by means of a frictioncollar 112, this being for the purpose -of providing for relativemovement between the jaws, it being evident that the jaw 103 will have atendency to remain in any position assumed until positively movedtherefrom. The jaw member 104 is connected by roller 99 in con-A oted tothe frame plate 37 at 115 and adapted to be actuated by means of a camlever 116, pivoted at 115 and carrying a cam roller 117, riding upon acam 118 on the shaft 36 (see Fig. 4),- said roller being held in contactwith said cam by means of a spring 119 secured at its upper end to therear end of the lever 116 and at its lower end to the frame bracket 38(see Fig. The levers 114 and 114 are yieldingly connected near theirlower ends by means of a spring 110, connected at one end to the lever114 and at the other end to a pin projecting. from the lever 114', thisconnection permitting the parts to yield and thereby prevent breakage ordistortion in case of a jam.

Through the described mechanism, the jaw member 104 is adapted to beperiodically raised and lowered and t-he lower jaw moved therewith whenthe jaws are in fully closed or fully open relationship. In the upperposition, said jaws are in open relationship (see Fig. 20) Cand adaptedto receive a wrapper p 121 as the same is cut off from the web 45 andarranged between said jaws, a sto-p and guide pin 120 being provided toprevent said wrap'- per from entering too far between the jaws and tohold said jaws in proper relative position, said pin 'being of arcuateform and being secured to the lower jaw, from which it extends upwardlythrough a slot 130 in the upper jaw. Saidjaw 103 is formed with ashoulder 122, which partially :to-rms said wrapper by bending the edgeupwardly, as show n in Fig. 22, as manifest-ly will occur when saidwrap-per is inserted t-o the full extent between the jaws and thelatter. are closed together. A lip, or guard, 123 is provided on theupper jaw 104.

Aft-er the wrapper has been placed-upon the lower jaw, as justdescribed, the upper I jaw is moved downwardly by the link 113 andlevers 114 and 114 until it is brought against the lower jaw, asindicated in Fig. 22, thus gripping the edge of the wrapper 121,continued movement then forcing the lower jaw downwardly until thewrapper is arranged in posit-ion above a block 124, which is Hanged att-he bottom as indicated at 125 and secured to thebed plate 15 by meansVot screws 126 extending through flanges 125 (see Fig. 7). Said block124 has a concavity 127 formed in the top thereof, of proper size toreceive the articles tobe wrapped, in the present instance mints or likecandy, indiciprocation of the link 113 and levers 114- and 114', itbeing evident that on account of the loose mounting of the member 104,106, the latter will be moved away from the member 103, 105 before saidlast-mentioned member is mo-ved upwardly, such upward movement of thejaw 103 being effected by means of a pin 129 on the part 106 of theupper member. After the transfer mechanism has been brought to the fullup positiomthe web is fed forward through the intermittently actuatedfeed rolls heretofore. described and another wrapper is cut off andplaced between the jaws 103, 104, whereupon the cycle of operation ofthe latter is repeated.

As the wrapper is positioned upon the block 124, a row of mints 128 istransferred from a tray 131z which is positioned upon a supporting plate132 projecting rearwardly from the frame. The mechanism for performingthis operation will now be described, reference being had particularlyto Figs. 5, 7, 8 and 2O to 22, inclusive.

Opposed arms 133 are mounted upon shafts 134 having bearings 135 and 136extended upwardly from the plate 15, the rear ends of said arms beingformed as collars 137, slidable upon said shafts 134 and being groovedas indicated at 138 for the reception of studs 139 carried in the endsof actuating levers 141, which are centrally pivoted upon vertical studs142 arising from the plate 15. The rear ends of said levers 141"areprovided with cam rollers 143, riding upon cams 144 upon the verticalcam shafts 31 and 32, the form of said cams being such as to reciprocatethe arms 133 upon the shafts 134, causing them to grip the front row ofmints in the tray 131 when in the rear posit-ion and to release the samewhen in the forward position, i. e., above the block 124, rocking motionbeing imparted to said arms in manner which will presently be described.Springs 150 are connected to the forward ends of said levers 141 and tothe plate 15 and serve to hold the rollers 143 in Contact with the cams144, as clearly shown in Fig. 5. Said arms are connected by links 146with a lever 147, pivoted at 148 to a downward projection 149 beneaththe bed plate 15, said li-nks being held in parallel relationship by across bar 151 and said arms 133 being connected to the links 146 bymeans of an elongated pivot rod 140 (see Fig. 21), the connection thuspermitting relative movement o said arms 133 longitudinally of the shaft134. The lever 147 is rocked by means of an arm 152, rigid therewith andextending beyond the pivot 148, said arm carrying a cam following roller153 engaging a cam 154 on the cam shaft 23 (see Fig. 6). A spring 155,connected with a pin 155 extending between the links 146, tends to holdthe lever 147 in down.

position and the roller 153 in contact with said cam 154, said springbeing connected at its lower end to a rod 156 extending between saidplates or uprights 14. It will be apparent from the foregoing that saidarms 133 are given both rocking and reciprocating movement, so timed asto cause them to grip a row of mints when in the rear position and torelease it in the forward position, in manner which will be readilyunderstood.

For the purpose of preventing disarrangement of the mints 128 as thesame are removed from the tray 131, I provide a spring lip 157,

pivotally mounted at the forward end of the support 132 and normallyheld in the position shown in Fig. 7 of the drawings by means of aspring 158, connected thereto and to a pin 159 projecting downwardlyfrom the bottom of said supporting member 132. This lip eX- erts ayielding pressure against the mints as the same are lifted out of thetray and it will be evident that this device prevents the striking ofsaid mints against a rigid part, such as the forward wall of the tray,as might readily occur without it.

'1` he' mints having been placed upon the wrapper positioned upon theblock 124, the next operation is vthe wrapping thereof and the mechanismfor performing the first stages of this operation will now be described,reference being had especially to Figs. 6, 7, 8, 20 and 22.

A jaw member 161 is pivoted at 162 to the block 124 and is provided witha rearward eX- tension '163,pivoted at 164 to a connecting rod 165,pivotally connected at its lower end to a lever 166, which is pivoted onthe shaft 148 and has a rearward extension 167, carrying a cam roller168 held in contact with a cam 169 on the cam shaft 23. A spring 171 ismounted on the rod 165 and is compressible between the bottom ofthe bedlate 15 and a shoulder 172 on the lower end o Y said rod, said springbeing compressed when the jaw 161 is closed, thereby steadying theaction, and expanding when the jaw is to be opened, thereby assisting ineffecting the opening movement. A spring 170, connected to said lever166 and to the cross rod 156, tends to hold said lever depressed and theroll 168 in contact with the cam 169 (see Fig. 3). The form of said cam169 is such as to first bring the jaw 161. into the position shown inFig. 6, after which it is removed, as shown in Fig. 7, to permitoperation of a co-acting jaw 17 3, the action of which will be presentlydescribed, said jaw f 161 being then again brought into action,l as

124, as clearly shown in Fig. 2. A spring 178 is mounted on said rod 174in the manner of the spring 171 on the rod 165 and said rod 174 isconnected at its lower end with a lever 179, which is pivoted at 181 tothe frame and has a rearward extension 182 carryinga roller 183previously stated, the jaw 161 is brought into action a second time uponeach wrapping operation` the final relation witlithe jaw 173 being shownin'Fig. 8. The wrapper 1s thus arranged as shown in Fig. l10 of thedrawings and the next operation thereon is the closing 0f the ends, asshown in Figs. 11 and 12. This is accomplished by mechanism which may beclearlyunderstood from an inspection of Figs. 5 and 13 to 19, inclusive,to which attention is now directed.

Co-acting reciprocating devices are positioned at theopposite ends ofthe block 124 in spaced relation thereto, said devices each comprising aplunger 185, slidably mounted withinbearing members 186 secured totheplate 15, said plungers having a plurality of fingers 187 pivotally`secured to projections 188 formed in pairs at the forward end there-4of. Said lingers are of bellcrank formation, having laterally extendingportions 189 disposed within an interior groove 191 formed in acollar-192, slidably mounted vupon the plunger 185 and having anexterior circumferential groove 193, in which is disposed av` head 194on a lever 195, pivoted on-the4 vertiL cal shaft 142 andhaving arearward eXtension 196, carrying a roller 197, contacting with a cam 198on the vertical cam shaft 31,

i 32, a spring 199 being connected to said lever extension 196 andadapted to hold saidv roller 197 in contact with said cam 198. A sleeve201 is slidably mounted within the plunger 185 and a rod 202 is mountedfor limited sliding movement within said sleeve, a collar 203 beingpositioned upon the rear end of said rod 202 and provided with a groove204 in which-isdisposed a stud 205, carried at the forward end of,alever 206, which is pivoted to a stud ,207,-projecting upwardly f roma standard 208,/said lever having a rearward lprojection 209, carrying acam following roller 211 contacting with a cam 212 on the verticalcamshaft 31', 32, the opposed lever extensions 209 being drawn towards eachother by a spring 213 connected at its opposite ends with arms 214,rigid with said lever extensions 209. The' plunger 185 is held againstrotation by means of a screw 215', eX-

tentling through the top of the member 186 and into a slot 216 insaidfplunger,'the rear end ofthe plunger being threaded, as indicated at217 and adapted to have a collar 218 screwed thereon and secured indesired position by means of set screws, 219. The sleeve 201 is alsothreaded at its rearend, as indicated at 221, and adapted to haveacollar 222 screwed thereon, the rear end of the plunger 185 being cutout, as indicated at 223, to receive said collar 222 and a spring 224,which is compressible between said collar and shoulder 225 in theplunger 185. A spring 226 is mounted on the rod 202 between the collars222 and 203 and said rod is guided and limited in its relativereciprocatory movement by means of a pin 227, projecting therefrom'andtaking into a slot 228 in the sleeve 201. A spring 229 is positionedwithin the collar 203, which is closed at one end, as indicated at 231,said spring being compressible between said end 231 and the outer endofthe rod 202, the latter having a pin 232 projecting therefrom andtaking into a slot 233 in said collar 203.

v The operationof said reciprocating devices l will be clear from theforegoing description `and the steps thereof are each illustrated indetail in Figs. 13 to 16, inclusive. In the re- *tracted position, theparts are arranged as indicated in Fig. 16. The levers 195 and 206 arethen actuated tomove the entireasseinbly inwardly', enoughl relativemovement being permitted between said plunger and collar to open thelingers 187, in the manner indicated in Fig. 13. Said collar 192 is thenslightly compression of the spring 224. The innerend of said sleeve 201is flanged, as indicated at 234, and its outer surface is concave, asindicated at 235. This surface acting upon the ends of the wrapperforces the end of the wrapper inwardly against the outermost mint 128 inthe row being wrapped. When the opposed sleeves 201 have moved inwardlyas far as permitted by the candy, 'the rod 202 is further advanced, thisbeing permitted by compression of the spring 226, and the wrapper endsare tightly pressed against and ioo caused-to conform to the shape ofthe end mints, the final condition of said wrapper being clearlyillustrated'in Fig. 12. It will -be evident that with this mechanism thewrapper ends are tightly interfolded and pressed into the `depressionsin the mints, so that therevare no irregular projecting portions andsaid ends will permanently remain in the condition in which they arearranged by the machine. kAs hereinbefore explained, Athis is highlyadvantageous when the packagesare to be dispensed through a vendingmachine and, obviously lis beneficial in any event as the packagest usforxnedare com- Ylao pact and rm so that they may be readily hanf.

dled and the contents are protected in the manner intended. After thefinal operation on the wrapper, the devices just described are returnedto the position shown in Fig. 16, the lingers being moved at the end ofthe stroke from the distended position lshown in Fig. 15 to theretracted position shown in Fig. 16, thus providing clearance for themechanism employed for removing the package from the block 124, whichmechanism will next be described.

Attention is now directed to Figs. 1 and 20 to 22, inclusive, whichperhaps best illustrate the package removing mechanism, which comprisesa pair of pivoted arms 236, connected together by a spring 236 andhaving inwardly extending studs 237 on the inner ends thereof and beingadapted to be actuated to grip the ends of the package, lift and carrysaid package to a pointof discharge and then release the sameinaccordance with a cycle of operation which will presently becomeapparent. Said arms 236 are pivoted respectively at 238 and 239 to aplate 241,

'which is slidably mounted in a slot 242 in av bar 243, which isprovided with an inclined slot 244 at the rear end thereof andisysupported by a rod 245 disposed within said'slot and carried byspaced arms 246, carried upon 'a shaft 247'journaled in forwardextension 249 of the bracket 109. Said shaft 247 is given rocking motionby means of. a link 251, secured to the end thereof and connected with aconnecting rod 252, which carries a spring 253 between a lower shoulder254 and a sleeve 255 into which said rod extends, the upper end of therod carrying a laterally projecting pin 256 disposed in a slot 257 insaid sleeve 255. This yielding connection takes up any shocks or jarswhich might result from obstruction of the parts actuated by said rod252 and associated mechanism. The upper end of the member 255 is pivotedat 258 to a lever 259 (see Fig. 4), said lever being pivoted on a rod261 projecting from an upper part of the frame and carrying a camfollowing roller 262 riding' upon a cam 263 carried bythe cam shaft 36.f

Reverting now to Fig. 22, it will be ob served that the plate 241 haslaterally projecting arms 264, which are secured to 11p-' right arms 265disposed inwardly from the arms 246 and carried by a shaft 266 journaled in the bracket extensions 249, a friction collar 267 beingpositioned upon a collar 268 fast with said shaft 266 and said arms 265.Said A,shaft 266, being idly mounted, is adapted to be rocked throughthe arms 265 and the friction provided by said collar 267 serves to holdlsaid arms in any position assumed until positively moved therefrom -byaction of the mechanism with which they are connected. Said plate 241 isslotted at 269 and 271, as clearly shown in Fig. 20, and is held withinto 27, inclusive. Y vrlage 277 is formed with a series'of apertures thebar 243 by means of pins 272 and 273 extendingthrough said slots. Thearms 236 have lateral projections 274, the projection of one arm beingabove and that of the other being below the plate 241, and the innerends of said projections are pivoted on the pin 272. It will now beapparent that movement of the bar 243 under rocking motion impartedthrough the arms 246 will cause the arms 236 to turn on their pivots238, 239, thus moving the free ends of said arms toward or from eachother. for the purpose of gripping and releasing the packages, which Ihave indicated by t-he reference character 275. As shown in Fig. 22 andin Fig. 8, the arms 236 are in separated relationship and ready to bemoved inwardly to grasp a package 275. Actuation of the shaft 247 inclockwise direction, viewing Fig. 22, then moves said arms to positionwith the studs 237 at the opposite ends of said package. The initialreverse movementof the shaft 247 then causes the bar 243 to moverelatively to the plate 241, thereby turning the arms 236 on theirpivots and causing them to grip the ends of the package, the relation ofthe parts during this part of the operation being shown in Fig. 20.Continued movement in the same direction causes the arms 236 tolbelifted, this being accomplished by the action of the pin 245 in thelinclined slot 244 andresulting in clearing 173. The package is heldduring the remain- Y der of the forward motion of the mechanism Aunderconsideration and at the end of the stroke there is a sudden reverse,tending to separate said arms 236 to permit release of said package,this motion also serving lanother purpose, which 'will later bedescribed. The package falls into a chute 276 at the front of themachine, which is of such form as to turn said package in endwisedirection and to` direct the same into a tray `131 arranged iniinclinedpositionupon 'a carriage 277, movably mountedl upon inclined tracks 278supported from the table 11.

Said carriage 277 is adapted to be moved by gravity along -said tracks278 with a step `motion, the mechanism forcontrolling said motion beingshown in detail in Figs. 5- and 23 The upper side of the car- 279 andapawl 281`is `mounted adjacent the carriage position, being pivoted at282 upon a bracket 283 projecting from the inner track 278. Said pawl'has a projection 284 adapted to extend into one of the apertures 279,being urged to this' position by means of a spring 285, connected at 286with the pawl and to a pinl 287 on the bracket 283. Said pawl is adaptedto be intermittently actuated to withdraw the projection 284 from saidaperture 279. After a package 273 has been positioned in thetray 131 onthe carriage 27 7, the carriage is permitted, through this mechan ism,to advance one step, so as to be in position to permit the positioningof a second package on the tray immediately behind the first one, thepawl, after being momentarily withdrawn, being immediately released andentering the next following aperture 279, toward which it is urged bythe spring 285. The mechanism for controlling said pa`wl 281 comprises abar 288, pivotally connected at 289 tothe pawl and connected at itsopposite end to a collar 291, loosely mounted on the shaft 247. Saidcollar carries a laterally projecting pin 292, disposed beneath the link251, which impinges momentarily thereagainst in the suddenreverse actionoccurring at the end of the outward movement ofthe bar 243, thisoperation having been hereinbefore referred to in connection with therelease yof the packages 275 by the arms 236. 'Inasmuch as said link isimmediately moved away after striking the pin-292, the spring 285 ispermitted to .jrestorethe pawl 281 and consequently said collar 291 tothe initial position in which the carriage is held in'adjusted positionuntil the next package has been deposited on the tray.

I provide means for automatically stop-o ping the operation of themachine after the tray carried by the carriage 277 has been'completelyilled,'this mechanism comprising "an angular member 293, pivoted at 294to the pawl 281 and connected by a bar 2,95 to a lever 296,.pivoted onthe inside of a plate 297 projecting from the bed plate 15,.

Said lever is rigid with an arm 298 arranged behind a pivoted lever`299, the lower end of which is normally in contact withy a pedal 301,which is `carried by a bar 302 pivoted at 303 to -a projection 304depending from the 'bed plate 15,

the opposite end of said bar being connected with a bar 305 extendingrearwardly beneath said bed plate and having a beveledy portiony 306`atthe rear end thereof adapted to acty u'pon a-p-awl 307 associated withthe clutch mechanism v22 on theshaft 17 to thereby disconnect saidclutch and stop the'operation of the machine see Fig. A spring 308tendsto pull down the end of said bar 305,

which is pivoted at 148 (see Fig. 6), said' spring being connected atits lower end to the rod 156. The rear end of said bar 305 is normallyheld in raised position by means of the lever 299 when the lower endthereof is ar-'V ranged upon the pedal,301, but when the cagriage 277 isadvanced to the position shown in Fig. 5, the rear portion 309 of themember 293 rides over'theend of said carriage and the bar 295 ismovedforwardly by means of a A'spring 311, Connected to the rear end ofsaid bar and to a pin 312 projecting from beneath This obviously causesthe arm 298, associated with the lever l296, to knock out thelower endof thev lever 299, thereby permitting the pedal 301 to rise lunder theiiiiuence of the spring 308 acting -upon the bar 305. The rear end ofsaid bar 305 is disposed 1n a guard 305', positioned upon a cross rod306 extending between the uprights 14. The clutch may be engaged bymanual depression of the pedal301 and it will be observed from Fig. 23that the lever 299 is extended upwardly above the plate 15 so that theclutch may be manually thrown out, if desired.

The track 278 is supported from the table 11 by means of angular members314, 315, 316 and the carriage 277 is supported upon the track 278 bymeans of rollers 317 and 318,

there being two ofthe rollers 317 on the inner side of the carriage and,in the present instance, but one roller 318 on the outer side thereof.

l Inasmuch as the machine hasA been described in the order of thesuccessive steps of' Y the operatiomit is thought that an extendeddescription ofthe' operation, as such, will not be necessary and it isbelieved that the following brief review will sufce to give a cles to bewrapped, might be supplied to the machinein other manner if desiredand'that the machine might be placed in line with feeding, sorting, orother mechanism, in accordance with factory conditions.

The n'i'achine may then be started by operation of the lever 299,forpedal 301, permitting the clutch 22 to become engaged, the engagementbeing ,effected by a spring-mecha,
